研究目的:

主要研究目的:与利多卡因比较,评估氯普鲁卡因表面麻醉在气管镜检查中抑制呛咳反应的有效性。 次要研究目的: 1. 探索氯普鲁卡因表面麻醉对抑制气管镜检查后复苏期间呛咳的抑制效果; 2. 评估患者满意度、舒适度; 3. 评估呛咳对检查操作的干扰程度; 4. 分析检查过程中呛咳对生命体征的影响程度。  

Objectives of Study:

Primary Objective: To evaluate the efficacy of prilocaine surface anesthesia in suppressing the cough reflex during bronchoscopy compared with lidocaine. Secondary Objectives: To explore the effect of prilocaine surface anesthesia on suppressing coughing during the recovery period following bronchoscopy. To assess patient satisfaction and comfort. To evaluate the degree of interference caused by coughing during the procedure. To analyze the impact of coughing on vital signs during the examination.

药物成份或治疗方案详述:

本试验研究药物为局部麻醉药用于表面麻醉。受试者签署知情同意后,所有满足入排标准的受试者纳入本研究,按照随机分组,以 1:1 的比例随机分为试验组(3%氯普鲁卡因注射液)和对照组(2%利多卡因注射液)。 1、患者在准备间使用3ml局麻药,即试验组或对照组药物进行雾化10分钟; 2、雾化结束后入内镜室,开始麻醉诱导,统一为静脉全身麻醉:瑞马唑仑0.1mg/kg+奥赛利定2mg,患者入睡后,内镜室医生使用气管镜一边进镜一边喷药,在鼻腔、声门、隆突和支气管各喷洒2ml对应组的局麻药; 3、开始检查,麻醉助理全程记录患者呛咳评分、呛咳次数等指标,并记录不良反应和并发症,在检查结束后对患者进行VAS评分; 4、若发生严重氧饱和度下降(<80%)给予面罩辅助通气,必要时给予丙泊酚2-3mg/kg。 

Description for medicine or protocol of treatment in detail:

The investigational drug in this trial is a local anesthetic used for topical anesthesia. After obtaining informed consent from the subjects, all those who meet the inclusion and exclusion criteria will be enrolled in the study and randomly assigned to either the test group (3% prilocaine injection) or the control group (2% lidocaine injection) in a 1:1 ratio. In the preparation room, patients will use 3 ml of the local anesthetic (either the test or control drug) for nebulization for 10 minutes. After nebulization, the patient will enter the endoscopy room, where general intravenous anesthesia will be induced: remimazolam at 0.1 mg/kg + oxycodone at 2 mg. Once the patient is asleep, the endoscopist will use the bronchoscope and spray the corresponding local anesthetic (2 ml) into the nasal cavity, glottis, carina, and bronchi while advancing the scope. The examination will begin, and the anesthesia assistant will record indicators such as the patient's coughing score and the number of coughs throughout the procedure. Any adverse reactions or complications will also be documented. After the examination, the patient will be assessed using the Visual Analog Scale (VAS). In the event of severe oxygen desaturation (<80%), mask ventilation assistance will be provided. If necessary, propofol at 2-3 mg/kg will be administered.
